android - ADB Command to set volume?

Question

Is there any Adb command to set the volume to a particular value? I know that we can do

adb shell input keyevent 

for volume up and down but i want to set it to a particular value. If I change it it DB then I have to reboot the device for the changes to be reflected so i do not want to go that path. Isn't there any API where I can change the value without having to restart it and having to be dependent on Volume up and Down?

Answer 1

media shell command can also be used:

media volume:  the options are as follows: 
    --stream STREAM selects the stream to control, see AudioManager.STREAM_*
                    controls AudioManager.STREAM_MUSIC if no stream is specified
    --set INDEX     sets the volume index value
    --adj DIRECTION adjusts the volume, use raise|same|lower for the direction
    --get           outputs the current volume
    --show          shows the UI during the volume change
examples:
    adb shell media volume --show --stream 3 --set 11
    adb shell media volume --stream 0 --adj lower
    adb shell media volume --stream 3 --get

The first example is probably the one you were looking for (but it probably didn't exist at the time of asking)
